Body A in Figure weighs 102 N, and body B weighs 32 N. The coefficients of friction
Question:
Body A in Figure weighs 102 N, and body B weighs 32 N. The coefficients of friction between A and the incline are ?s= 0.56 and ?k= 0.25. Angle θ is 40o. Let the positive direction of an x axis be up the incline. In unit-vector notation, what is the acceleration of A it A is initially (a) At rest,
(b) Moving up the incline, and
(c) Moving down the incline?
